Application led J' une 9, 1915. Serial No. 33,092.

To all whom t may concern Be it known that l, MORRIS LowY, a citi- Zenof the United States, and a resident of the city of New York, in thecounty of New York and State of New York, have invented certain new anduseful Improvements in Bed-Springs, of which the following is aspecification.

The present invention relates to improvements in bed-springs, having awoven wire or spring constructed bottom or web. In springs of this typethe free ends of the wire strands of the woven fabric are clampedbetween binding or retaining strips, which are riveted together andconnected by helical springs with the angleiron transverse bars of thesupporting frame. In constructing these bed springs, obviously each setof binding or retaining strips must be provided with two sets ofregistering apertures, that is one set for the clamping rivets and theother set for the helical springs. ln a similar manner must in theangle-iron transverse bars of the supporting frame be formed openingsfor the helical springs, care being taken that these openings be inalinement with the corresponding perforations in the binding orretaining strips. The perforating and riveting work must be performedwith great care in order to obtain a durable and marketable article.Although special tools and jigs are used for the perforating operations,it may be stated that a large part of the manufacturing and assemblingexpense is taken up by the perforating and riveting work.

One of the objects of the present invention is to reduce the cost ofproduction of the bed springs by doing away with the perforating andrivetingrwork, or by reducing such work to a possible minimum, therebyproducing a structure which is simple, dura# ble and convenient toassemble.

With these and other objects in view, which will more fully appear asthe nature of the invention is better understood, the same consists inthe combination, arrangement and construction of parts hereinafter fullydescribed, pointed out in the appended claim and illustrated in theaccompanying drawings, it being understood that many changes may be madein the size and proportion of the several parts and details ofconstruction within the scope of the appended claim without departingfrom the' spirit or sacrificing any of the advantages of the invention.

Two of the many possible embodiments of the invention are illustrated inthe accompa* nying drawings, in which Figure 1 is a plan view of a bedspring constructed in accordance with the present invention; Fig. 2 is avertical section taken through a portion of said spring on a largerscale; Fig?) is a plan view, partly insection, of the detail shown inFig. 2; Fig. 4 is avertical section taken through a modiiication of theinvention; and Fig. 5 is a plan view, partly in section, of themodification shown in Fig. 4f.

Broadly speaking, the invention consists in embedding the free ends ofthe wire strands of the fabric, forming the spring mattress bottom, andalso reinforcing bars in retaining strips which consist of a suitablecomposition, metal, alloys of metal or any other suitable substancewhich forms, upon setting or hardening, a rigid or stiff bar; thereinforcing bars being disposed in front of those portions or sectionsof the retaining strips which are engaged by the means which connect thesaid retaining strips with the angle-iron or other transverse bars ofthe supporting frame.

Referring now more particularly to Figs. 1 to 3, inclusive, the numeral10 indicates the angle-iron transverse bars of the supporting frame.These members are attached, for instance by rivets, to corner bracketsor blocks 11, having sockets, in which are seated the usual side bars 12of the frame. The brackets are provided with sidewardly extending lugs13, which rest upon the side rails 14: of the bedstead in the usualmanner. The spring mattress bottom is made of a suitable fabric,indicated at 15, the free ends of its wire strands being embedded inretaining strips 1.6, in which are also embedded reinforcing bars 17. Ineach retaining strip is formed in rear of the reinforcing bar 17 a rowof apertures 18 for a purpose hereinafter to be described. The retainingstrips may be made of metal, alloys of metal, compositions 0r othersuitable substances which form, when set or hardened, a rigid or stifflbar. The process of embedding the free ends of the wire strands and thereinforcing bars in the bodies of the retaining strips dependsentirelyrup'on the nature or lproperties of the material or which saidstrips are formed. For instance, if the material be metallic, theelements to be embedded are placed into a suitable mold, the moltenmetal or alloys of metal poured thereinto, and left to congeal. Into theapertures 1S extend the inner ends `of helical stretcher springs 19.Both ends of these springs are bent, for' instance, into hook-shape, asclearly shown in Fig. 2 of the drawings. One of the ends of each spring19 is hooked into an aperture 1S, and the other end into a perforation20 in one of the angle-iron transverse bars of the supporting frame.

The operation and assembling of the bed spring is obvious from theforegoing.

It is to be observed that by this improvement a very simple, inexpensiveand practical ineans is provided for connecting the wire mattress bottomwith the transverse angle-iron bars of the supporting frame, and that bythis construction the riveting work is entirely Vdone away with and theperforating work reduced to a possible minimum, in the springillustrated in Figs. 1

t'o 3, inclusive, there being no other rivets Vbut those which securethe cerner brackets er blo'cl'rs U11 to the angleeiron transverse bars10. Inasmuc'h as the reinforcing bars 17 are disposed in front of theinner hookshaped ends of the helical stretcher springs 19, the latterwill be safely anchored in the said retaining strips, and the saidstretcher springs cannot tear 'or break away portions of the retainingstrips if subjected to undue tension by a heavy weight placed upon themattress bottoni.

A modification of the invention is illustrated in Figs. -fl and 5 of thedrawings. This structure differs from the one above described in thatthe retaining strips lack the apertures 18 above mentioned, the innerhook-shaped ends of the helical stretcher springseinbracing the inneredges of the said retaining strips. The reinforcing bars serve in thiscase also a twofold purpose, to Wit: to strengthen the retaining stripsand to provide an anchorage for the helical stretcher springs.

It is obvious that instead of the woven wire fabric bottoms, any othersuitable bottoins, for instance wire link bottoms, may be made rise ofwithout departing from the spirit of the invention.

That I claim is A bed spring 'comprising a supporting frame includingtransverse end members, a wire fabric bottoni hai'fing the free ends ofits wire strands inclosed by mold-fashioned retaining strips, helicalstretcher springs having their inner ends hooked onto said retainingstrips and their outer ends conneeted with said transverse end members,and reinforcing members embedded in said retaining strips and disposedin front of the curved portions of the hook-shaped inner ends of saidstretcher springs.
